SPECIFICATION forming part of Letters Patent No. 625,163, dated May 16,1899.

Application tiled February 1,1899. Serial No. 704,093. (No model.) l

To all whom, it may con/087%:

Beit known that LPIRRE HAnRsrrga citizen of the United States, residingat Chicago, lin the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Street-Cleanin g Machines forBoulevards, Parks, and Paved Streets,` of which the following, whentaken in connection with the drawings accompanying and forming a part ofthis specification, is a description sufficient to enable those skilledin the art to which it pertains to understand, make, and use the same.

This invention relates to that class of cleaners designed to gather orpick up articles, either dirt or other material, from the ground `anddeposit the same in a receptacle provided therefor.

The object of this invention is to obtain a' machine which shall beparticularly arranged for and fittedV to maintain park-boulevards andasphalt-paved streets in a cleanly and presentable condition; and forthe purpose of carrying out the above-named object I have obtained amachine whereby dirt can be picked from the ground,either street orboulevard, and deposited ina receptacle therefor carried by and formingan element in the machine. I have also obtained a machine from which thereceptacle used can be readily taken and another and like receptaclesubstituted therefor. I have further obtained a machine in which theseveral adjustments necessary to retain the parts in proper relativeposition as the machine is used and such parts are worn are simple,easily made, and not liable to get out of order.

In the drawings referred to and wherein a letter of reference applied todesignate a given part is used to designate such part throughout'theseveral figures wherever it appears, Figure 1 is an end elevation of acleaningmachine embodying the invention; Fig. 2, a vertical sectionalview adjacent to the driving-wheel of the machine, showing the apron andshovel and adjustable shoe of the machine in proper relative position;Fig..3, a

side elevation of the upper end of the frame of the apron and of aU-shaped frame to which the apron-frame is attached and to whichU-shaped frame also the axles of the machine are secured; Fig. 4, an endelevation of the lower end ofthe apron-frame with the' 7 an endelevation of a dirtreceptacle which is removably attached to themachine.

A, Fig. l, is the non-rotatable axle ofthe machine, on which the wheel aisrotatably mounted'in the ordinary way. Axle A (one on each side of themachine) is secured to Y the upper end of the U-shaped frame B.

b, Fig. 2, is the horizontal member of U- shaped frame B, andb avertical member thereof.

h2isa slot in vertical member b of U -shaped frame B, and b3 is a holetherein through which the axle A extends and is attached thereto.

C is a dirt-receptacle having the projection or lug C on each endthereof, respectively.

C2 is an arm rigidly secured at one end thereof to vertical' member b ofU-shaped frame B.

C3 is a recess in the outer end of arm 02,1'n which recess theprojection or lugC' of the receptacle C rests when such receptacle ismounted on the machine. The forward part of the receptacle rests onhorizontal member h ofthe U-shaped frame B. The receptacle C willtherefore maintain its position by gravity on such arms C2 C2 (one oneach side of the machine) and member b of U -shaped frame B.

C5 is the handle by which the machine is propelled.

D is the apron-frame of the machine.

d is a bolt extending through the apronframe D, near the upper endthereof, andthroughV the slot h2 in vertical member b of U-shaped frameB.

f d', Fig. 2, is the apron of the machine.

Apron d is secured to the apron-frame D, the upper end of the apronextending to above the receptacle C when such v'receptacle is placed onthe machine, as above described and asfillustrated in Fig. 1.

d2 is the'lower end of apron d', formed t0 receive on the upper facethereof the upper edge of the adjustable shovel N, hereinafterdescribed. (See Figs. 2 and 4.)

E is a side bar (there being one thereof on each side of the machine)adj ustably seeurin g lthe apron-frame D to the upright member b' ofU-shaped frame B. The adjustment secured bythe side bars E E is toobtain proper tension on the brush-chain J, hereinafter described.v Theadjustment of the upper end of the apron-frame D, which is obtained bybolt d extending therethrough and through the slot h2 in verticalmembers b b', is to obtain proper relative position between the apron dand the brushes L, hereinafter described, at the Lipper end of suchapron.

e is a bolt extending through the side bar E and apron-frame D, and e'is a bolt extending through slot e2 in side bar E and through verticalmember b of the U-shaped frame B.

F is a wheel secured to one of the wheels a a of the machine to rotatewith such wheel and having internal gear-teeth thereon.

G is a wheel secured on shaft g to rotate therewith, having externalgear-teeth engaging with the gear-teeth in wheel F.

g', at the upper end of vertical member b',

forms the bearing in which shaft g is rotatably mounted. (See Figs. 2and 3.)

H H are sprocket-chain wheels rigidly secured, respectively, to shaft gon each side of the machine to rotate therewith.

H', Fig. 2, is an ordinary clutch, by means of which the wheel G isthrown into and out of engagement with the wheel F, so as to rotate ornot, as preferred, the sprocket-chain wheels H, there being twosprocket-wheels H, one adjacent to each of the upright members h b ofU-shaped frame B.

I I are sprocket-chain wheels rigidly secured to shaft t' to rotatetherewith. Shaft t is rotatably mounted in ihe frame D, near the lowerend thereof, as illustrated in Figs. 1, 2, and 4,

J J are brush -chains extending, respectively, over sprocket-wheels H HI I and having secured thereon at intervals the brush sockets or framesK K.

L L are the brushes, by means of which the material gathered on shovel Nis elevated on apron CZ and delivered therefrom into the receptacle C inthe operation of the machine.

Brush sockets or frames K K, respectively, comprise bed 7c, sides 7c7c', and turned-in edges 162702. The brushes L are inserted in the brushsockets orframes K by being forced thereinto or slid, so that when agiven brush becomes worn it may be removed and a new one substitutedtherefor.

M, Fig. 2, is a roller mounted on shaft m in adjustable frame M to comein contact with the chain J, adjacent to the lower end of the apron d',to adjust the brushes to the apron at such lower end of the apron. v'

m is a bolt extending through slot m2 of the frame M' and throughapron-frame D.

By means of the adjustment last above described of the rollers M M withreference to the lower end of the apron-frame, such rollers forcing thechain to an adj usted position and the adjustment of the apron-frame Dtoward the brushes at the upper end of such frame by means of bolt d inslot b2, hereinbefore described, any desired adjustment of the entireapron d with reference to the br'ushes passing over it is obtained.

N is a shovel adj ustably secured to the apron-frame B, at the lower endof such apronframe, by means of bolt n, passing through slot n'.

n2 is a loop or pocket on theunder side of the shovel N, into which loopor pocket the forward end of the shoe O extends, such forward end of theshoe being lettered O3. Slice 0 is adjustably secured in place by boltO', extending through slot O2 in such shoe and through the apron-f rameD, such bolt having a nut thereon.

The shoe O is not used by me when the machine is employed for gatheringrefuse, litter, or dirt on an asphalt -paved boulevard or street, itspurpose being when used to prevent the forward edge of the shovel Npenetrating a street or boulevard,when the surface thereof is soft ordusty, beyond a determined distance. To show the attachment of theforward end O3 of shoe O to the shovel N, such shovel N is shown inFigs. 1, 2, and 4 at a.

greater incline than I prefer to place such shovel ordinarily. Anyadjustment of the ineline of the shovel N is readily obtained byloosening the nut on boltn in slot n'. (Well shown in Fig. 4L.)

This machine is particularly adapted for use on park-boulevards in placeof the ordinary sheet-iron scoops now employed for that purpose and isdesigned to be pushed by a man or boy by handle C5 about the street. Thereceptacle C is made removable, so that when the same is filled it canbe lifted from the machine and placed to one side of the boulevard and aduplicate receptacle substituted therefor on the machine or to beremoved from the machine at any time and the contents thereof emptiedinto a cart or other receptacle.

By obtaining the several adj ust-ments hereinbefore particularlydescribed I am able to make a machine which will well perform the workit is intended to do and so easy to manipulate and propel that a man orboy may readily move or push it about a street or boulevard and maintainthe same in an aceeptably clean condition even when many horses aredriven thereover.
